BOOMS

KEY FEATURES

BLACK SERIES

The latest generation is produced in high-tech technology whereby the boom arms and the head are “melted“ together with aerospace-standard glue.

FRONT-END

iFRONT 2.0 - The lightest Front-End on earth

INSIDE GRIPPED TAIL with STANDARD FITTING

DETAILS

BLACK SERIES

The current BLACK generation is manufactured in high-quality BONDED.TECHNOLOGY. In this process, tubes and front end are “welded” using special adhesive used in space travel. The iFRONT 2.0 front end, with flex and stiffness tailored to the needs of specific users, is installed for greater comfort and simple operation. The BLACK range includes two individual bend curves, whereas both short lengths have a modern PROGRESSIVE BENDCURVE and the reduced, comfortable tube diameter of 28 mm. All other lengths have a conventional bending line and a 30 mm tube diameter. For reliability and comfort, the DOUBLE PIN LOCK system helps to firmly fix the boom length in place while preventing the tubes from being twisted. Thanks to the different bending lines, the BLACK series fits with almost all sail types from all brands.

The technical masterpiece which makes all Duotone booms even more functional: iFRONT 2.0 the latest front-end of the next generation.

It doesn’t just look slimmer and smoother, the iFRONT 2.0 is also a whopping 35% lighter than its predecessor! With 345 grams it is the lightest front-end on the market!

90% of all other booms on the market are equipped with the same front-end from China, which usually differs only in color or design details. Especially in major components we at Duotone are investing heavily in research and development to be far ahead of the competition. A prime example of this is the completely redesigned and absolutely unique iFRONT 2.0 front-end; it combines maximum ease of use with highest functionality, lowest weight and guaranteed durability. For the first time the construction of the iFRONT 2.0 combines the advantages of both concepts in one front-end:

A Vertical stiffness: Unlike other front-ends we use 50% longer stainless steel axle-bolts which are directly connected to the side walls. Thus we obtain a maximum vertical/torsion stiffness, which results in an extremely direct connection/transmission of boom to mast (= maximum performance).

B Horizontal flexibility: The partially recessed center of the collar gives the iFRONT 2.0 a kind of hinge function, so that the collar fits to any mast diameter without any gap (= very smooth on the mast and extremely slip resistant). We know of no other front-end that fits so smoothly around the mast and thus effectively protects the mast.

This exceptional fit is guaranteed on SDM as well as RDM masts as the iFRONT 2.0 can easily be adapted through the exchange of 2 different friction pads.

It is an open secret that different conditions require front-ends with different vertical/torsional stiffness so that the rig can develop its maximum potential yet the comfort doesn’t suffer. For this reason, we deliver the new iFRONT 2.0 in two different stiffness options that are tailored to the individual disciplines and requirements:

Stiffness I with 15% vertical flexibility has a very low flex for direct power transmission yet maximum control and comes with all RED, SILVER, as well as GOLD and PLATINUM (up to 170) booms. Stiffness III with 0% vertical flexibility for uncompromizing torsion-stiffness and maximum performance on large sails comes with all GOLD and PLATINUM (190 and up) booms. Of course, we remain true to our promise of long-term compatibility even with the iFRONT 2.0. Therefore it is 100% retro-compatible with older Duotone booms that can be upgraded and tuned.

MINIMUM WEIGHT AND UNMATCHED FEATURES! Especially on carbon booms most brands integrate the fittings into the tail-end to generate a clean look. We prefer external fittings to achieve 3 crucial advantages:

Much lower weight
